Answer:
-69x-66
Step-by-step explanation:
1) given: a₁=-4x-1; a₂=-9x-6; a₃=-14x-11. Find: a₁₄-?
2) a₁₄=a₁+13d, where d - the difference between neighbor-terms;
3) d=a₂-a₁; ⇔ d= -9x-6+4x+1= -5x-5;
4) a₁₄= -4x-1+13*(-5x-5)= -69x-66.
7/12 and 1/2
Get the common denominator
Multiply 1/2 by 6
7/12 and 6/12
Answer:
$9
Step-by-step explanation:
The slope of the given line is -4/5. The line perpendicular to that line will have a slope that is the opposite reciprocal. In other words, the perpendicular slope will be 5/4. If it passes through (4, 12), we have an x and a y value to use in y=mx+b. y is 12, x is 4, and we have a slope of 5/4. Filling in accordingly:

and 12 = 5 + b. So b = 7. Rewriting with our new slope and b value,

. And there you go!
Your answer would be c and d because coefficients are the numbers that go in front of the variables. Have a nice day I hope this helped :)
